PROBLEM TO BE SOLVED: To provide an evaluation device that evaluates an object using an electroencephalogram acquired from a subject.SOLUTION: An evaluation device includes: an electroencephalogram acquisition part 11 for acquiring electroencephalogram signals of a plurality of subjects, each being acquired from each of the subjects; an intensity data generation part for generating intensity data, based on the electroencephalogram signals, representing an intensity of a signal component in a predetermined frequency band or representing a relationship between intensities of signal components in a plurality of frequency bands in time series; a correlation data generation part for generating correlation data representing in time series cross-correlation coefficients that are found by calculating a cross-correlation coefficient between pieces of intensity data at respective times between the plurality of subjects; and an output part for outputting evaluation data representing a degree of synchronization of electroencephalogram variation between the plurality of subjects based on the correlation data.SELECTED DRAWING: Figure 1 |
